Title: Ground excavation and agitation device
Inventor: UMEMOTO YASUHIRO
IPC: E01C23/12
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To make work execution efficient by mounting an excavation and agitation shaft on a support member, with the axial line of the shaft kept at an angle with excavation surface. SOLUTION: A excavation and agitation device 1 is connected to a connecting tube 4 and this tube 4 is mounted on the arm end of the work device of a construction machine via a mounting plate. The surface layer of the subsoil is excavated and agitated under the operation of excavation and agitation shafts 3 and 3', with an arm moved vertically. Furthermore, a solidifying agent such as cement, cement milk and lime added to the subsoil is agitated and mixed with soil, due to the excavation and agitation operation, and then solidified to form an improved subsoil. Also, during the excavation and agitation operation, blades 6 attached to the excavation and agitation shafts 3 and 3' extend to a level under a support member and the appearance of an un- excavated part is thereby prevented. Thus, a construction work on a pitch basis can be executed within the range of R0 .  As a result, a non-excavated part does not appear at the excavation and agitation process, and the pitch- based work can be executed. Also, pushing resistance drops, thereby allowing an efficient work.
